Sorry - a not so very good Sunday ice update. #Arctic sea ice extent is easily the *lowest* on record to kick off a new year (JAXA data)... 🌊

• about 610,000 km² below the 2010s mean
• about 2,160,000 km² below the 1980s mean

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.
